  2. focus_gain(focus_type)

  3. mouse_motion(rect), where [rect.x, rect.y] is where the user clicked.

  4. mouse_press(button, rect)

  5. mouse_release(button, rect)

  6. key_press(key, mod_keys)

  7. key_release(key, mod_keys)

  8. window_resize(rect), where [rect.w, rect.h] is the size of the window.

  9. joy_motion(joystick_id, axis_id, axis_value)

  10. joy_press(joystick_id, button_id)

  11. joy_release(joystick_id, button_id)
